Error reading tags: Error: WTf is type entity_types

[lerokko]

Adding the folder entity_types in data\NAMESPACE\tags throws the error "Error reading tags: Error: WTf is type entity_types"

Entity types are a thing. TBF I only learned about them today and they are not displayed in the F3 menu, but they exist. I thought it ways entities, but not its entity_types. https://minecraft.gamepedia.com/Tag#Entity_type_tags
